Compare the store’s current “regular” price with dated prices that were actually advertised.
SALE CHECKER
Check if that sale is actually a sale.
Paste a product link. LessBother checks what the store is claiming now and searches dated archived copies of the exact listing when they exist.
WHAT THE CHECKER CAN PROVE
A sale badge is not evidence.
Not enough evidence is a real answer. If the archived history is thin, LessBother says that instead of inventing a confident verdict.
